REPORT ON THE FOR AMINIEE R A.

and the immense specimens which have been referred to were obtained at Stations 155 
and 156, very near the Antarctic Ice-barrier, depth 1300 fathoms and 1975 fathoms 
respectively. In the Pacific Ocean it is also plentiful, its presence having been noted 
at six Stations south of the equator, 1070 to 2600 fathoms, and at seven north of the 
equator, 1850 to 2950 fathoms. 
Reophax guttifera, H. B. Brady (PI. XXXI. figs. 10-15). 
Reophax guttifera, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 49.

Test elongate, nearly straight; composed of several (3 to 8) inflated segments. 
Segments variable in contour, typically pyriform ; broadest near the base, and tapering 
to a narrow stoloniferous tube at the point of union with the succeeding chamber. In 
small specimens the base of the segments is often truncate or even somewhat concave ; 
in larger examples the chambers are less regular in outline and the connecting stolons 
are wider. Texture coarsely arenaceous ; exterior rough ; colour yellowish-brown. Length, 
seldom exceeding x^th inch (L6 mm.). 
The series of drawings (PI. XXXI. figs. 10-15) conveys more effectively than many 
words a just idea of the range of form exhibited by this species. The smaller specimens 
are more easily recognised than those of larger size ; yet even the largest and most 
irregular preserve to some extent the normal pyriform contour of the segments, and 
their comparatively thin stoloniferous connections. These characters, together with the 
nearly straight test, serve to distinguish the longer individuals from such forms as 
Reophax adunca , which they otherwise somewhat resemble. 
Reophax guttifera is an exceedingly rare species. The figured specimens are all 
from a single locality, Station 323, South Atlantic, east of Buenos Ayres, 1900 fathoms. 
It occurs also in the cold area of the Faroe Channel, 540 fathoms ; and a single some- 
what doubtful example was met with at Station 85, off Palma, Canaries, 1125 fathoms. 
Reophax spiculif era, H. B. Brady (PI. XXXI. figs. 16, 17). 
Reophax spiculifera , Brady, 1879, Quart. Journ. Micr. Sci., vol. xix., N. S., p. 54, pi. iv. 
figs. 10, 11. 
Test elongate, straight or arcuate ; consisting of a few (3 to 6) cylindrical 
segments. Shell-wall composed of siliceous spicula arranged side by side, and firmly 
cemented together. Spicula often protruding more or less from the base of the segments. 
Length, f^th. inch (L0 mm.). 
This is one of the many species of Foraminifera that give evidence of considerable 
selective power in respect of the material employed for the construction of their tests.
